acinar cells
Holocrine
apocrine
G cells in the stomach lining secrete gastrin hormone. This hormone helps in the regulation of gastric acid secretion and motility in the stomach.
epithelial tissue
Peroxisomes are not glands.They are small organells.
Unicellular exocrine glands are certain cells that are specialized for secretion. Even though they are single cells and have no ducts, they are still considered to be exocrine because they secrete their products directly to a specific site. The most common unicellular exocrine glands are the goblet cells that secrete mucus in the epithelium of your trachea and digestive tract.
Holocrine
The most common type of exocrine glands are the sweat glands. These glands are found throughout the body and are responsible for producing and secreting sweat to help regulate body temperature.
The Golgi apparatus is found in eukaryotic cells. It will be more pronounced in cells involved in secretion.
apocrine
Apocrine glands have portions of cells containing secretions pinched off from the main cell body. When these pinched-off portions are released, they contain the secretions produced by the cell.
Paracrine secretion enters the interstitial fluid and affects neighboring cells in the same tissue. It plays a role in local signaling between cells within a specific tissue or organ.
Holocrine glands are the type of secretion that undergo mitosis and rupture. The cells accumulate secretory products until they burst and release their contents. Examples include sebaceous glands in the skin.
Simple columnar epithelium is the type of epithelium designed for absorption and secretion found throughout much of the gastrointestinal tract. It is characterized by tall, closely packed cells that have microvilli to increase surface area for absorption and goblet cells for secretion of mucus.
the pancreas is a single organ, which spits into two limbs in the dog. it consists of 2 types of cells. one type which make hormones such as insulin (the endocrine cells of the pancreas) and another type of cells that make digestive enzymes for excretion into the gut (the exocrine cells of the pancreas).
Liver , salivary glands .
Insulin is synthesized in significant quantities only in beta cells in the pancreas.
